Code test case
Verify that an assembler
class that implements
the IAssembler interface
creates the exception
handlers and injects the
configuration object values
into those domain objects.
Implemented?
Yes
Feature that is implemented
The following code demonstrates how the Logging-
ExceptionHandlerAssembler class, which implements
the IAssembler interface, creates a LoggingException-
Handler object. The Assemble method in the Logging-
ExceptionHandlerAssembler class injects the configuration
data from the LoggingExceptionHandler object
into the LoggingExceptionHandler domain object. The
process is similar for all the exception handlers that
implement the IExceptionHandler interface.
public class LoggingExceptionHandlerAssembler
: IAssembler
{
public IExceptionHandler
Assemble(IBuilderContext context, Exception-
HandlerData objectConfiguration, IConfigurationSource
configurationSource, ConfigurationReflectionCache
reflectionCache)
{
LoggingExceptionHandlerData castedObjectConfiguration=
(LoggingExceptionHandlerData)objec
tConfiguration;
…
LoggingExceptionHandler createdObject = new
LoggingExceptionHandler(castedObjectConfigur
ation.LogCategory,castedObjectConfiguration.
EventId,castedObjectConfiguration.Severity,ca
stedObjectConfiguration.Title,castedObjectCon
figuration.Priority,castedObjectConfiguration.
FormatterType,writer);
return createdObject;
}
}
